nisms, of which the following is a full, clear,

. and exact specification;

My nisms.

It has among its objects to improve the construction of binding mechanisms, and especially those of the type adapted to use invention relates to binding mechain connection with grain shockers, wherein a twine guide deflects the twine extending between the knotter and the binder needle out of the path of a bound shock as the latter is discharged from the machine.

A Jfurther object of my invention is to provide twine guiding and positioning means of improved construction which, when used in connection with a grain shocker, deflect theV twine to the desired height and hold the same in the desired position even when the twine is struck by the tops of long sheaves in a discharged shock, but from which the twine may be readily disengaged without danger of breaking the saine when in the normal operation of the machine such disengagement is desirable, as, for instance, when thev first sheaf of the following shock is deposited in the shocker cradle. v

A still further object of my invention is to provide a twine guide especially adapted to cooperate with a binding needle, as that of a shocker, the twine guide acting upon the twine fed out from the needle with increased efliciency and being movable into engagement with the needle without having its twine engaging and deflecting function deleteriously affected by the contact therewith.

I attain these objects by providing twine guiding and positioning means of improved construction adapted to be carried, ifv desired, upon the compressor arm of a shocker, which twine means cooperate with a bindiing needle in an improved manner and are 1 sired elevated position-thereof despite engagement of the same by the tops of the sheaves forming the shock, all as hereinafter more fullv set forth.

In the accompanying drawings, I have shown one embodiment which my invention may assume .in practice, illustrating the same in connection with a grain shocker of the type described and claimed in my copending application, Serial No. 742,535, tiled January 17, 1913.

Figure 1 is a rear elevation of the shocker with the twine guide thereon, showing the needle in its two positions. Fig. 2 is a detail view showing the side elevation of the twine guide and the cooperating frame member. Fig. 3 is a top plan view of the twine guide and the cooperating frame member.

In the construction shown, I have illustrated a shocker mechanism of the type described andclaimed in the above mentioned application comprising a wheeled frame 1 upon which reclines a rearwardly dumping shock receptacle or cradle 2 operated through link and crank connections 3 by the knetter shaft 4C; a compressor arm 5 being pivoted at 6 upon the side of the frame and operated through a cam 7 on the knotter shaft, engaging with an extension 8 on the compressor arm to `cause .the latter to cooperate with a transversely movable needle 9, which, in turn cooperates with a knotter 9 and is likewise driven from the knotter shaft; an improved twine guide hereinafter described being carried upon the compressor arm.

As shown in Fig. 1, this twine guide is in the form of a coiled spring 10 positioned upon the side of the compressor arm 5 at a point adjacent its upper end. The free end of this spring 10 is extended downward and laterally and then protruded in an opposite' direction to form a resilient curved hook 11; the end 12 of which is disposed at an angle to the compressor arm 5, as shown in Fig. 3. As illustrated in Fig. 2, the coiled portion or body of this spring is attached to the outer edge of the compressor arm 5 by a suitable triangular shaped plate 13 having a flange 14C attached to the compressor arm by bolts 15 and a projection 16 on its opposite or peaked end which serves to prevent the twine from being caught in the spring when the latterl is pulled torward from the position shown in F ig. 3. It is to be noted that the longitudinally extending, bowed strengthening band 17 upon the compressor arm 5 is disposed parallel to the latter throughout the greater vportion of its length and terminates at a point adjacent the twine guide, the upper end of the same being attached to the compressor arm by one of tho bolts 15 used to attach the twine guide and the 'free end 19 ot' the twine guide extending diagonally between the same and the compressor arm 5. It is further to be noted that a vertically extending member 18 on the machine trame protrudes upward from the body of the frame member in a plane substantially parallel with the compressor arm when in elevated postion so that the curved or hooked end of the twine guide passes close to the same and in its elevated position is back of the same, as shown in Fig. 3.

When, in the course of the operation of the shocker, the shaft et is rotated, rotating the cam 7, the compressor arm S is thrown over to compress the sheaves in the cradle and move them away Afrom the point of the needle 9 as the latter moves downward to coperate with the knotter 9a. As the parts thus move downward, the needle 9 will obviously force the twine guide hook 11 out of its path, and the latter, being resilient, will return to a position above the needle as soon as the latter has passed it; the needle, the compressor arm and twine guide occupying' the positions shown in full lines in Fig. 1 while the knot is being tied. In a like manner, when the needle has completed the binding operation and while both the needle and compressor are moving backward, the twine guide on the latter will be again forced out of the path of the needle. In this instance, however, it will spring back into a position in which it underlies the needle so that as the part-s continue to move backward, the twine fed out from the end of the needle will be caught over the hook 11 on the twine guide 10 and elevated to the position shown in dotted lines in Fig. 1, wherein it is held out of the path of the tops of the sheaves as the cradle 2 is thrown to shock discharging position by the link and crank connection 3. Should the tops of the sheaves in the cradle strike.

it and leaving it extending across the frame above the cradle in the position shown in dotted lines in Fig. 1. lllhen, however, the iirst sheaf oi' the next shock is deposited in the cradle, this sheatl will'engage the twine and, due to the resiliency and construction of the guide, will cause the twine t-o be disengaged therefrom without danger of breaking the same; the twine then being pulled downward over the hook 11 and the latter yielding until it occupies the position shown in dotted lines in Fig. 2, wherein the twine is freed so thatit can go to the bottom of the cradle and lie beneath the sheaves as they are piled in the latter. Obviously, when the knotter shaft 4 is again rotated, the operation of the twine guide will again be just as described, the latter operating automatically to lift the twine after each actuation of the needle.

It is to be noted that in this construction, through the coperation ot the frame member 18 and the hook shaped twine positioning member, even although the tops of the sheaves in the cradle should engage the twine, the same will be prevented from disengagement from the twine guide and will be held in the elevated position desired until the next sheafis deposited in the cradle. It is further to be noted that due to the provision of a twine guide which is freely movable and resilient, the same is always free to move downward when the twine is carried down by this sheaf; the twine in this case slipping over the curved or hooked end of the guide. Attention is further directed to the fact that due to the provision of the projection on the guide holding plate, the twine is etectually prevented from becoming caught in the coils of the spring even when the free end of the latter is pulled forward.

lVhile I have described one embodiment of my invention in this application, it is to be understood that this embodiment is susceptible of being modified without departing from the spirit of my invention.
